ABSTRACT

Background: in recent days, drug-induced sleep endoscopy (DISE) has been used to identify the site of obstruction in patients with obstructive sleep apnea. Objective: In this study our main goal is to evaluate the role of drug-induced sleep endoscopy (DISE) in OSA patients. Method: this prospective case study was carried out at Asgar Ali Hospital from 2017-2021. Where a total of 100 patients who complained about snoring and difficulty in respiration during sleep were included as a sample population. During the study all patients undergone DISE technique. Results: Most of the patients belongs to 31-36 age group, 71% and 54% were male and 46% were female. 61% patients were overweight. Followed by 23% had hypertension, 15% had diabetes, 30% had hypothyroidism, 10% had smoking status. In addition followed by DISE techniques, snoring only seen in 12% cases where oxygen saturation was 95-97%. Followed by 3% had Central sleep apnea and 85% had complete obstruction. Besides this, 35% had Involuntary leg movement and 5% had severe restlessness. Moreover, majority site of obstruction notice in lateral wall, 30%. Followed by 15% were soft palate, 5% were tongue base and laryxs. Besides that, in 20% cases, multiple site of obstruction were noticed where 15% had lateral wall and soft palate and 5% had lateral wall, soft palate and tongue base. Conclusion: DISE has an emerging role in identifying the site and characteristics of obstructions associated with OSA. The procedure provides important information about dynamic changes in the upper airways during sleep.
